Teleidosaurus is an extinct genus of carnivorous metriorhynchoid crocodyliform from Middle Jurassic (late Bajocian to early Bathonian stage) deposits of Normandy, France.

The type species was named Teleosaurus Calvadosii [Sic] by Jacques Amand Eudes-Deslongchamps in 1866;[3] however, it was his son, Eugène Eudes-Deslongchamps who erected the generic name Teleidosaurus later in 1869[4] for Teleosaurus calvadosii.

Teleidosaurus joberti from the Great Oolite Formation is a junior synonym of T. calvadosii.

Phylogenetic analyses do not support the monophyly of Teleidosaurus.

[1][7] Once considered a metriorhynchid, Teleidosaurus was later recovered as non-metriorhynchid metriorhynchoid.
